Key Points
- An IPM strategy needs to deal with all pests.
- Biological controls (usually predators and parasites) occur in NZ cropping areas and will help to control slugs and aphids.
- Insecticides targeting one pest can interfere with the control of other pests.
- Under an IPM approach aphids can be chemically controlled by ensuring beetles don’t come into contact with broad spectrum insecticides by using seed treatments such as Gaucho and by using selective aphicides such as Pirimor.
- Suitable Chemical options are available and can include selective pesticides (baits or sprays), seed dressings and border treatments.
- All pests need to be identified in order to understand the best management practice for control.
